T0 all 'whom it may concern: l v

Be itl known that I, J AMES WILLIAM MoR- nisoN, a subject of the King ofGreat Britlain and Ireland, residing at Bayley street, Staleybridge, inthe county of Lancaster, England, have invented new and use fulImprovements in Yarn-Winding Machines, of which the following is aspecification'.

My said invention relates to yarn winding apparatus, that is, to theclass of machine for re-winding yarn such as yarn from ring framebobbins, or from reject cops, and generally for re-windingpyarn orthreads.

My apparatus is intended to re-wind yarn into cops the same as, orsimilar to, mule cops, and mule spindles are utilized. The

construction is such that the gage of the spindles is very small, adistance apart as `vlittle as 1% inches being possible. Winding may beon the bare spindle, or on paper tubes, as may be desired. Y

I preferablymake my frame in sections and I support the mule spindles infixed rails. With respect to the spindles, I employ a movable bar or rodcarried on swing arms or otherwise and having yarn guides, such bar orrod being influenced to control the building of the cops. A coppingmotion including a quick drop cam acts on a vchain to influence the baror rod, and I also combine with the other elements means to act on saidchain to divertor affect it with the object of shortening or adding toits length und so regulating the`length of chase during the process ofbuilding, and so serving as a chase'regulating device. I insert aquickly laid binding thread, as in a mule wound cop, und to lay thisthread in, I preferably'arrange to arrest the windingon during the timethe quick drop cam puts in the binding thread. A stop motion is alsoprovided to anrest the ymachine on breakage of an end, &c.

My yarn winding apparatus is vhereafter fully described with referenceto the attached; drawings, wherein:

Figure 1 shows a side elevation of one section orl length of the framewith certain parts omitted. Fig. 1L shows a detail of Fig. 1. Fig. 2 isa front elevation, certain of the parts being again omittedv to preventconfusion. Fig. 3 is a detail showing the rotary chase infiiiencingdevice. Fig. 4 shows a side elevation of the frame from the right-handwith certain parts broken away omitted. 5 and 6 are detail viewsindicating the stop motion. Figs. 7 and 8 illustrate a slightmodification in connection with the stop motion. Figs. 9, 10 and 11 arediagrams, indicating how the copping chain is influenced to affect theaction of the copping motion, and consequentl the movable ar, andwhereby the length o chase is regulated.

Respecting Figs. 9, 10 and 11, Fig. 9 shows the chase regulating deviceacting as a shortening motion and influencing the chase as at thecommencement of a set of cops, the chase indicated being the minimum onewhen starting the bottom; Fig. 10 shows the position when the cop bottomis fully formed the chase regulating device having moved to such anextent that it has .ceased to influence the chain and Vso the chase isat its longest. Fig. 11 indicates the cop as when fully wound, a nosingdevice (carried on the chase regulating barrel) having gradually comeinto action to influence the chase to slightly shorten same as the copsi approach completion and the nose is formed und to conpensate for theradually decreasing diameter of the spin es. i Fig. 12 is a. detail planview of the swinging bar orrod carrying the yarn guides, and alsoshowing the chain barrels and supporting shaft and part of the stopmotion -mechanismx Fig. 13 shows the vtin roller and its clutch gear,&.c. A Figs. 14A and l5 are detached detail views showing the cam shaft,cams, the clutch, &c. Figs. 16 to 19 .illustrate in' detail a modifiedarrangement for driving the lower front 'shaft according-towhich saidshaft is driven fromv the tin roller shaft and the use of a clutch onthe lower front shaft is' dispensed with. The figures lare'frag'men-vtary -view's but are sufficient to explain the variation. Fig. 20 is adetail elevation indicatinghow the brake leverV may be held out ofaction or allowed to come into action vto give continuous orintermittent winding,

and Fig. 21' is a plan view of the holding out ings A5, driveeach-,'tinlrllerthrough' a clutch, as -forexample "bya conical-'frictionclutch' b', the tin rol er being thrust into frictionai contact withlthe clutch on 'the 5 shaft b to effect driving' of the spindles and beinbraked or' arrested when vtheI means whic thrust in thetin roller.l aremoved out.

Y The shaft. b2 is driven bye band from the main driving. 'sliaftc51961"otherwise and said shaft. b2. carries thel conical. clutch -b. A

brake lever d is pivoted at d and` this brake lever has a curved fbraking surface ed* with leather faceldaf. Said brake'lever has arearward extensiondand a-forward exten'- so a weighted :lever arm igfixed on the 'shaft g2`and this.V forkg2 thrusts the tin roller b \in.to.contact'with the-clutch b and Aso the tin roller 'is driven. ,Similarly-when vthe contact'piece df occupies the bite e inthe cam, the rearwardextension jd* y'is elevated and the lever g acted on'torock the shaftv gand cause such. a movement of the forkg2 as al# lows the tin roller 'toAmove outof gear.4 Thus-,the brake lever dnot 'ony insuresthedisengagement of the clutch 'but it -arrests momentum of-the1ltinroller. The bite'-e in the cam e, is ,presented once duringevery 40 revolution ofthe camshaft f and-thi'soccurs 'j ustvat the timethe uick'drop takes place i 'and so-the 'bindin t read is laid in by aquick -descent,1an with the spindles al" rested.

The main shaft c'fis the drivingshaft, as

explainedV and this drives '.by means -of ai band. h from the pulleylaf-to the'pulle'yA h2 on the stud shaft h3," and' o'n v'said stud.shaft isa. spur pinion k* which meshes with the largev gear wheel f onthe lower front shaft" f.- :This manner '.of driving may -be obviouslyvaried. The dered fast or loose on the'v shaft f by means of aclutchf2,worked bya clutchlever f3,

for a purpose to beexplained later.V

On the shaft f is .fixed-- the copping cam i forming art of the' coppingmotion,- the bowl i ci) whichcoppingmotion bears on said cam andwhich'copping motion has the usual nut 2 on the screw shaft i3 slowlyrotated by the usual ratchet motion it, the main copping lever being.fulcrumed at i and the chain passing over the usual bowl i' and thenupward to indirectly infiuence 55 the bar or rod -s carrying the yarnguides gear wheel ff 'is ren'- by reason of said chain iacting on the`pul- A ley4 j. The chain is attached to the drum `'or pulley j on theupper shaft j and this sha t'jalso carries a second drum or pulley j2'wlch, by a chain j, suspends the swing 'frame mec anism supportingy themovable b'aro'r rod lc with yarn guides. lThis swing frame mechanismconsists of an upper` arm k and lower braced arms k k' suspended bylinks k? k-,Which links are pinned by set screws on the shaft llc?x (seeFig. la) which shaft is supported in bearings. .It-willi be not1ced thatthe braced armsv 'c c (during building) swing onthe shaft k. A The armla v1s pinned on the rock shaft k3. The.

i length'of chain js'is adjustably attached at jto a projection fromtheupper arm k'and passesunder an 'adjustable bowl k* (carried in one ofthe arms k) and thence onto the drum-` or pulley j to which its end isattached. Thus, the swing frame mechanism counterbalances the weight ofthe-com lete cop ing motion. The windin -of, 'o' `the chain z `from thedrum or pul ey j causes the winding-on'of the chain gia on the pulleyjf, with consequent gradual raising of the yarnbar or rod la", while therockingof the shaft j dueto the copping motion vibrates theyarn guide'barvkrwith respect tothe mule spindles and so controls the buildingofthe cops.1 v

iVere lno mechanism interposed, the copping motion" and mechanismdescribed would' givea uniform chase, with a quick drop and an arrest ofthe spindles during the quick drop.V I therefore combine orin-4 clude' achase'regulatingv device, or devices, in order to be able to regulatethe chase at will, and this'v takes the form of'a chain deectng device@secured to vthe .rotatable shaft'y' and capable of being adjusted or'set as required. 1 When commencing-to build, this device Z deiiects thechain i (see Fig. 9) and so shortens Athechain and diminishes `thelengthk of the chase proportionately with the lamount the chain isdeflected. A s the copV bottom progresses 'or is built-up, the

length of chase is `gradually increased,until such time as the ldevice l(due to rotary movement) gradually ceases to influence the chase as thecop bottomis fully formed (see Fig. 10). Correspondingly I may graduallyshorten the chase, or` compensate for de crease indiameterof the mulespindles, by applying'a curved and inclined nosing piece or chaseregulator ZC fixed to thedrum or .pulley j which gradually comes intoaction as the lcop approachescompletion, and this is' well shown by Fig.11. The yarn is directed onto the spindles by suitable yarn guides, asfor example the yarn guides k adjustably fixed in the bar or rod los.

A. stop-motion is requisite to stop the machineywhen an end breaks. Thismotion is controlled from -the copping cam shaft f.'

Each yarn or end passes over a' pivoted finger m hung or ivoted on a barat m', 'on a su port m, an the tension of the yarn norma y Y depressesthe forward end of such finger, and, causes the rear end to keepelevated, small drop-wires m3. Below said drop wires is an oscillatinbar n supported around the shaft j and roc ed thereon. The oscillatingbar n has a lever arm n connected thereto, and, to this lever arm, isjointed at n, a cranked lever o 'which is acted on by the connecting rodo jointed at o2 to the pivoted lever p pivoted about if'. The pivotedlever rf is acted upon by a cam p on the cam shaft f', and, as said camp revolves, the oscillating bar n is vibrated below the drop wires m. Solong as the drop wires remain elevated, the oscillating bar is partiallyrocked around the shaft j moving on that shaft which acts as a support,the cranked lever owhen acted on by the connecting rod o merely swingingor rocking the oscillating bar n below the dro wires. As soon however asan end brea the particular drop wire is lowered and obstructs theoscillating bar n and resists its swinging, and, therefore, the crankedlever o now turns on the fulcrum n and acts on a projecting stud qattaehedtoasecond connecting rod o and so compels movement or elevationof the latter. The result of this is, that the connecting rod acts onthe lever g2 and consequently on the clutch lever f3, which it rocks,and so disengages the clutch box f2 and stops the driving of the camshaft f. The cams p and e, are sotimed, that the clutch is disengagedabout'the time the tin roller b would be disengaged and braked, as isobvious.

As a modification, I might arrange to dispense with the drop wires ms(as in Figs. 4, 5 and 6) and cause the oscillating bar n to encounterthe tail end of the pivoted finger m hung on the bar m. The pivotedfinger m is normally maintained clear of the oscillating bar n by theyarn being passed below a guide t and then partly around the projectingshaped end of said pivoted finger m.- Immediately an end breaks, therear end of the finger m falls, and obstructs the oscillating bar n,with the same results before described. This modification is clear fromthe Figs. 7 and 8.

In order to automatically stop each frame when the cops are fully woundI may arrange to act on one of the pivoted fingers to depress the rearend. A suitable arrangement is indicated in Fig. 4, and consists of abent lever r, hinged at r', and having its forward end normallyvsustained just clear of one of said pivoted fingers m when the rear endof such finger is elevated. To the bent lever r is pivoted at 8 a leveror limb .s with a projection s2 which latches on any convenient part,and the lower end of the lever or limb s is suitably bent or'shaped asat s. When the braced arms lc', lc rise sufficiently high, as the copsap roach completion, a cross bar k1 on arms encounters the lower endof'the lever or limb s and unlatches the projection s2 and allows thelever r to fall and depress the pivoted finger m and so sto the machine.

To obvlate breaking down of the ends when winding on paper tubes, orotherwise,

and on completion of the cops, I may arrange to lower the arn guide baror rod lc to directthe yarn or a few turns onto the spindle at a lowerlevel than the base of the cop, and, this can be provided for bysuspending the swing frame k, c, lc', by a pivotd latch or levei s*pivoted to the member c at 85. When the latch or lever s* is unhooked,the frame k, la', c, turns with the shaft lc as the center of movement.The chain connection at j* is lowered along with the supporting arm k.Thus by unlocking or disengaging and lowering the latch or lever s, theyarn guide bar or rod w" can be lowered below the base of the cop andthen by lifting the handle d to set the machine in action momentarily afew turns wound on the spindle, all, as will be obvious from the dottedlines seen in Fig. 1. j

According to the modified arran ement depicted on Sheet 6, Figs. 16 to19, drive the pulley k2 by the band it direct from a pulley h" on thetin'roller shaft b2. The tin roller b is moved into gear with `a clutchmember b', as before, by a fork gz mounted on the shaft g, (see Fig. 17)and the pulley L* is fixed to the said tin roller b, which tin rollermay have a turned up edge bf to prevent the end driving band runningolf, as shown in Fig. 17. otation of the pulley turns the pinion h* andso drives the large pinion f. No clutch on the lower front shaft f isneeded, because, when the fork g2 moves away from the tin roller, thelatter is released and the pulley hx is not driven and no motion iscommunicated to the pulley h2. The clutch fork g2 is moved when theshaft g is rocked and this is brought about by acting on the lever q,which, in this case, is pinned on the shaft g. The lever q2* has anextension which engages the modified form of brake lever d* pivoted atdx and so works such brake lever applying the brake and taking it offwhen worked by the connecting rod (1*. This occurs when an end breaks,or when the cops are fully wound, because, upward movement of theconnecting rod q* works the brake lever q2* and rocks the shaft g todisengage the clutch. In thiscase I do not propose to arrest the tin,roller during the quick drop because for winding some classes of copsor for winding on tubes or bobbins it may be preferable or convenientnot to periodically arrest the tin roller during such time as thebinding length is put in.

40 to the lower spindle support a.

65 catch, etc.

In order to permit the winding of a few coils on the spindles belowk thebuilt-up cops priorto doiing, followin upon lowering of the yarn guidebark la y its frame, it is necessary to be able to release the brakelever (1P-say, by pressing same down, to take off the brake and to rockthe shaft g. u To allow of this being done, the connectin vrod g*passes' through an eye-bolt 2 in t e lever 1o g2* and its lower lengthliS baked uP by a s ring d" held on by adjustableA nuts. '1hus, when aset of cops is fully wound, the lever d* is depressed by hand, by actingon the handle d`5 to release the brake and rock the shaft g, the springdTx giving as the lever g2* is slightly pressed down. Itis obvious thatthe stop motion acts through the connecting rod g* to lift the lever g2*whenever the rocking bar n isv obstructed, and the stoppage of themachine is consequently brought about by applying the brake cl2x andmoving the fork g2 to release the clutch in connection with the tinroller b.

With regard to the construction of winding frame already fully describedwith reference to Figs. 1, 2, 3 and 4 and the detail views Figs. 5 to 15such frame can be most simply' arranged to giveeither continuous orintermittent Winding just as required, by

the adjunct or modification fully shown at Figs. 20 and 21. `This end isachieved by the provision of a lever 1X. pivoted at 2 on a bracket 3 thelever having a notched catch 4. This notched catch when in one positioncan engage a pin 5 on the brake lever d, and,

when in its other or dotted position,L is held clear of the pin 5. Thepivoted lever 1x can be held clear by means of a turn catch 6 @am e andso the clutch is not disengaged or the brake applied to the tin'roller.The result is continuous winding. It will be noted, that, even with thebrake lever d so held out of action, the mechanism kstill is effectivefor automatic stoppage (as for eX- yample when an end breaks) because inthat case the rod q when lifted elevates the lever q2, as before, whichin turn lifts the lever 1x and so releases the brake lever cl alto- 55.gether. For intermittent winding (i. e. ar-

resting of the spindle alternately) the levei l is simply raised out ofaction and made to occupy the position shown in dotted lines Fig. 20 andis held in that-position by the turncatch 6 holding down the outer endof the lever l". WVith the lever 1x out of action a condition exists asthough such lever 1 were non-existent. TheV Fig. 21 is a plan view ofthe pivoted lever 1x and the turn `I ldeclarethat.what I claim is-,v i
